STL File Modification for 3D Printing

Basically we experiment on three types of sample on the basis of their performance we select the sample and use for all

A. For SAMPLE 1
(Same gear ratio )

1.Hour hand.stl

(shaft circle to pentagonal)

2. Minute hand.stl

(shaft circular to pentagonal)

3. 12T gear small hole.stl

( inner shaft circular socket to pentagonal socket )

4. 12T gear big hole.stl

(Inner shaft circular socket to pentagonal socket )

5. 32T servo gear.stl

(adjust the inner socket that can be mount on s90 servo motor shaft )

B.For SAMPLE 2

(1:2 gear ratio )

(Hour hand.stl shaft circle to pentagonal)

2. Minute hand.stl

(shaft circular to pentagonal)

3. 12T gear small hole.stl

Increase Diameter

( inner shaft circular socket to pentagonal socket )

4. 12T gear big hole.stl

(Increase Diameter )

(Inner shaft circular socket to pentagonal socket )

5. 32T servo gear.stl

Decrease Diameter

32Teeth to 24Teeth
(adjust the inner socket that can be mount on s90 servo motor shaft )

C.For SAMPLE 3

(2:3
gear ratio )

(Hour hand.stl shaft circle to pentagonal)

2. Minute hand.stl

(shaft circular to pentagonal)

3. 12T gear small hole.stl

Increase Diameter

( inner shaft circular socket to pentagonal socket )

4. 12T gear big hole.stl

(Increase Diameter )

(Inner shaft circular socket to pentagonal socket )

5. 32T servo gear.stl

Decrease Diameter

32Teeth to 18Teeth

(adjust the inner socket that can be mount on s90 servo motor shaft )
